Oxidation state of Tungsten
Atoms of Tungsten in compounds have an oxidation state of 6, 5, 4, 3, 2, 1, 0, -1, -2, -4.
The oxidation state is the conditional charge of an atom in a compound: the bond in a molecule between atoms is based on the sharing of electrons, thus, if the atom’s charge virtually increases, then the oxidation state is negative (electrons carry a negative charge), if the charge decreases, then the oxidation state is positive.
Oxidation state of an ion W4+ = 4

Valence of W4+
Atoms of Tungsten in compounds have valence VI, V, IV, III, II, I.
Valence of Tungsten is an ability of an atom W to build chemical bounds. The valence is based on electronic configuration of atom: electrons participated in chemical bounds are known as valence electrons. In general the valence is:
The number of possible chemical bounds with other atoms
The valence has no sign.
Quantum numbers W 4+
Quantum numbers are defined by the last electron in configuration, for an ion W these numbers are N = 4, L = 3, Ml = 3, Ms = -½
